摘　　要：旋挖钻机广泛应用于桩基础工程施工中,针对旋挖硬岩钻进时传统钻头对岩石冲击、钻头振动以及取芯后甩筒取芯产生巨大噪音等问题,通过创新性将旋挖钻机与滚刀钻头相结合,采用专门设计的旋挖滚刀钻头对硬岩进行全断面碎裂研磨钻进,岩石碎成细粒状岩屑后用旋挖捞渣斗捞出,在成桩质量、工序管理、生产效率、绿色施工等方面都突显出了显著的成效,为实现旋挖入硬岩免噪绿色施工提供了一种创新、实用的工艺技术。Rotary drilling rig is widely used in the construction of pile foundation engineering.In order to solve the problem of huge noise generated by traditional drill bit during hard rock drilling and coring by rotary digging,the rotary drilling full section hob bit is designed to chip grinding drilling of hard rock by innovative combination of rotary drilling drill and hob bit.After the rock is broken into fine granular rock debris,it is extracted by the rotary dredging bucket.Remarkable results have been achieved in pile quality,process management,production efficiency,green construction,etc.It provides an innovative and practical technology for realizing noise-free green construction of rotary dredging into hard rock.
